Single ended shrouded output transformer
back to top
Over designed for single ended tube output circuits (triode, tetrode or pentode tubes).
Enclosed (shielded), 4 slot, above chassis Type "X" mounting, both end bells include knockouts for optional above chassis wiring.
Frequency response at least 20 Hz. to 20 Khz. at full rated power (+/- 1 db max. ref. 1 Khz.)
Insulated flexible leads 8" min.
All units (except the 1642SE & 1638SEA) include a 40% screen tap for Ultra-Linear, tetrode/pentode operation (if desired). The 1642SE & 1638SEA do NOT include this screen tap.
High quality laminations, (M6) grain oriented silicon steel.
Designed for general purpose or replacement use in single ended, tube output circuits.
Frequency response: 100 Hz. - 15 Khz (+/- 1db max. - ref. 1 Khz).
Open style with minimum 12" long primary & secondary leads leads.
All sizes use butt stacked cores (using 29M6 steel) with an air gap, to reduce D.C. core saturation.
Primary impedance range from 2,500 to 10,000 Ohms.
Secondary impedance range from 4 to 16 Ohms.
